Install heat insulation around both the gas and liquid pipes. Failure to do so may
cause water leaks.
Use heat insulation with heat resistance above 248 °F (120 °C). Reverse cycle model
only.
In addition, if the humidity level at the installation location of the refrigerant piping
is expected to exceed 70%, install heat insulation around the refrigerant piping. If
the expected humidity level is 70-80%, use heat insulation that is 3/4 in. (15 mm) or
thicker and if the expected humidity exceeds 80%, use heat insulation that is 13/16 in.
(20 mm) or thicker.
If heat insulation is used that is not as thick as specifi ed, condensation may form on
the surface of the insulation. In addition, use heat insulation with heat conductivity of
0.045 W/(m•K) or less (at [68 °F (20 °C)]).

3.2. Electrical requirement

The indoor unit is powered from the outdoor unit or branch box. Do not power indoor unit
from separate power source.
Refer to local codes for acceptable cable type.

4. SELECTING THE INSTALLATION LOCATION

Decide the mounting position with the customer as follows:
(1) Install the indoor unit level on a strong wall which is not subject to vibration.
(2) The inlet and outlet ports should not be obstructed: the air should be able to blow all
over the room.
(3) Install the unit a dedicated electrical branch circuit.
(4) Do not install the unit where it will be exposed to direct sunlight.
(5) Install the unit where connection to the outdoor unit or branch box is easy.
(6) Install the unit where the drain pipe can be easily installed.
(7) Take servicing, etc. into consideration and leave the spaces shown in [5.1. Installation
dimensions]. Also install the unit where the fi lter can be removed.
Correct initial installation location is important because it is diffi cult to move unit after it is
installed.
Install the air conditioner in a location which can withstand a load of at least 3 times the
weight of the main unit and which will not amplify sound or vibration. If the installation
location is not strong enough, the indoor unit may fall and cause injuries.
Withstandable weight (Unit weight x 3*)
Do not install the unit in the following areas:
• Area with high salt content, such as at the seaside. It will deteriorate metal parts, caus-
ing the parts to fail or the unit to leak water.
• Area fi lled with mineral oil or containing a large amount of splashed oil or steam, such
as a kitchen.
It will deteriorate plastic parts, causing the parts to fail or the unit to leak water.
• Area that generates substances that adversely affect the equipment, such as sulfuric
gas, chlorine gas, acid, or alkali.
It will cause the copper pipes and brazed joints to corrode, which can cause refrigerant
leakage.
• Area that can cause combustible gas to leak, contains suspended carbon fi bers or
fl ammable dust, or volatile infl ammables such as paint thinner or gasoline.
• If gas leaks and settles around the unit, it can cause a fi re.
• Area where animals may urinate on the unit or ammonia may be generated.
• Do not use the unit for special purposes, such as storing food, raising animals, grow-
ing plants, or preserving precision devices or art objects.
It can degrade the quality of the preserved or stored objects.
• Do not install where there is the warning of combustible gas leakage.
• Do not install the unit near a source of heat, steam, or fl ammable gas.
• Install the unit where drainage does not cause any trouble.
• Install the indoor unit, outdoor unit, branch box, power supply cable, transmission
cable, and remote controller cable at least 40 in. (1m) away from a television or radio
receivers. The purpose of this is to prevent TV reception interference or radio noise.
(Even if they are installed more than 40 in. (1m) apart, you could still receive noise
under some signal conditions.)
• If children under 10 years old may approach the unit, take preventive measures so
that they cannot reach the unit.
• Install the indoor unit on the wall where the height from the fl oors more than 70 in.
(1.8 m).
This product has an built-in WLAN adapter.
Refer to the Setting manual for wireless LAN control for air conditioning to decide on the
place of installation.

5. INSTALLATION WORK

CAUTION
• Do not hit or push the human sensor. This may lead to damage or malfunction.
• Do not touch the human sensor. Any scratches or dirt may lead to incorrect detection.
• Do not place large objects near the human sensor. Also keep heating units outside
the sensor's detection area.
Detection range of the human sensor is as follows.

5.2. Indoor unit piping direction
The piping can be connected in the 6 directions indicated in the following.
When the piping is connected to direction (2) , (3) , (4) or (5) , cut along the piping groove
on the side of the front cover with a hacksaw.

(3) Bottom outlet
5.3. Cutting the hole in the wall for the connecting piping
(1) Cut a 65 mm diameter hole in the wall at the position shown in the following.
(2) Cut the hole so that the outside end is lower (5 to 10 mm) than the inside end.
(3) Always align the center of the wall hole. If misaligned, water leakage will occur.
(4) Cut the wall pipe to match the wall thickness, stick it into the wall cap, fasten the cap with
vinyl tape, and stick the pipe through the hole.
(5) For left piping and right piping, cut the hole a little lower so that drain water will fl ow
freely.
